COMBINATION MECHANISM FOR ELECTR'ICLOCKS.

SPECIFICATION forming part of Letters Patent No. 608,322, dated August 2, 1,898.

Application iiled J'une 18,1898. Serial No. 683,785. (No model.)

To LZZ whom t may concern:

Beit known that I, HENRY GUY OARLETON, acitizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in a Combination Mechanism for Electric Locks, fully described and represented in the followingV specification and the accompanying' drawings, forming a part of the same.

This invention relates to an improvement in controlling devices for electric locks, and is particularly concerned with certain modifications in construction of controlling devices of the character set forth in my application, Serial No. 676,303, filed April 4, 1898.

The invention consists in certain parts, improvements, and combinations hereinafter described, and more particularly pointed out in the claims hereunto appended.

In the accompanying drawings, which constitute a part of this specification, Figure 1 is a vertical section taken o'n the line 1 l of Fig. 2. Fig. v2 is a verticalsection taken in a plane which lies at right angles to the plane in which Fig. 1 is taken. Fig. 3 is a section taken on theline 3 3 of Fig. 4. Fig. 4 is a section taken on the line 4 4 of Fig 3. Fig. 5 is a diagram illustrating the circuits employed.

1n the construction shown in the accompanying drawings, A indicates a lock-casing which is to be set in the woodwork of the door or in any other suitable place.

a ct indicates spindle, preferably two in number, which are suitably mounted in the casing before referred to and are operated by knobs ct or in any other suitable manner. Inasmuch as the spindles are similar in construction and operation the description of one of them and the parts connected therewith will serve for both. y

O11 the'inner end of each of the spindles o, is an arm a2, which is connected by a suitable pin a3 to a disk B, which is mounted on the spindle. The arm CL2 is connected to the spindle CL through the medium of a squared section or in any other convenient or desired manner. turns in its bearings the disk B will be turned therewith through the medium of its connection with the arm a2.

It is obvious that as the spindle a- The disk B is provided with a series of indicating devices, herein shown as nicks, though ridges, projections, or other similar constructions might be used, located on the Aperiphery of the disk and marked l to 15 inclusive, and with an additional nick marked 0. VThe nicks from 1 to 15 are spaced at regular and corresponding distances apart, but the nick marked O7 is arranged in the open space between the nick marked 1 tand the nick marked 15, and is spaced at a greater distance vfrom these `than they are from the adjoining nicks, so as to leave the periphery of the disk unbroken for some distance each side of it. 1 y v Suitably located in the interiorv of the casing, so as to cooperate with the nicked disk hereinbefore described, is a'detent, springpawl, feeling-pin, .or other similar device C. This pin is shown as located in an angular loop c', being retained therein by an enlargement o2 on its end. The pin is provided with a shouldercs, and between this shoulder and the angular loop before referred to is a spring c4, bywhich the pin is thrown forward, so as to bear upon the periphery of the disk referred to. The spring is sufficiently strong, so that as the spindle a and the disk B are turned by the knob ct the click which occurs as the detent drops into the successive nicks will be distinctly felt by the person operating the knob. The disk and spring-pin thus form an indicating mechanism by which the position of the circuit-controlling mechanism to be hereinafter 4described is ascertained and the combination operated so as to place the lookin proper condition to be opened.

The disk B is also provided with a series of perforations, lthere being one for each of the nicks l to 15 before described, and the pin a3 may be made to engage any desired one of these perforations. By this means, therefore, the position of the spindle c and the devices carried thereon with reference to .the disk may be varied and the combination changed. Y

Suitably located in the'casing is a stationary plate, preferably, though not necessarily, in-the form of a ring D. This'ringis formed of-any suitable insulating material, such as hard rubber or vulcanite. It is herein shown as supported from the lock-casing by means IOO of a suitable bracket D', but it may be supported in any other suitable or convenient manner and has embedded in it a conducting-section d?. The body of this conductingsection lies entirely within the surface of the ring, but its ends are exposed. In the space within the ring D is located a circular plate E, which is formed of any suitable conducting material-such, for instance, as brass. This circular brass plate is perforated at its center, and through this perforation the spindle u, before described, passes. The plate E has a notch c therein, and this notch is preferably entered by a projection d of the ring D, before referred to. Dy means of this projection and notch the plate E and the ring l) are or maybe securely fastened together with their surfaces lying in the same plane. \Vhile this construction and arrangement of the disk D and the plate E is a preferable and desirable one, it is to be understood that it is not a necessary one. The ring D and the disk E need not be secured together, nor need they be arranged with their surfaces in the same plane. It is sufficient if they are arranged in proximity to each other.

Mounted on each spindle a, so as to turn therewith, and insulated therefrom by collars F or in any other suitable manner are a series of circuit-controllers, preferably in the form of brushes II, I, and K. The brushes II and I are arranged to bear upon and travel on the surface of the ring D, before referred to. They are spaced apart a distance equal to the distance between the ends of the conducting-section (l2, heretofore described as embedded in the ringD. It is obvious, there fore, that when the ends of the brushes II and I are bearing upon the respective ends of the section dl these brushes will be in electrical connection through the section (l2, and that when they are not resting on the ends of this section they are not in electrical connection, because they are insulated from each other and the spindle by the collar F. The brush K is arranged to bear upon the conductingplate E at all times except when itis opposite the notch c, heretofore described, at which time, when the parts are arranged as shown, it bears upon the projection of the insulating-disk l). It is therefore in electrical connection with this plate E at all times except when it is opposite the said notch. The arrangement of the brushes lf, I, and K is such that when the brush K is opposite the notch c in the plate E the brushes Il and I will bear upon the ends of the conducting bar or section d, before described.

Suitably located iu the casing between the spindles u, before referred to, is a block I, of any suitable insulating material. Mounted on this block is a thin conducting strip or bar M, preferablyof metal, the ends of whichbear on the hubs of the brushes Il. This conductor is herein shown as angular in form; but itmaybe arranged in any suitable manner, so as to connect to form an electrical connection between the brushes Il Il. Another strip or bar O acts to electrically connect the two brushes K, before described. The block further carries a pair of contacts N, each of which forms a terminal for a circuit hereinafter to be described, and cach of which is in electrical connection with the brushes I, before referred to.

At I (see Fig. is indicated an electrical bolt-operating mechanism. This bolt-operating mechanism is similar to that set forth in my application, Serial No. 631,586, filed May 24, 1898, and need not herein be specifically described further than to say that when a current is passing through magnet-coils p' they are caused to attract their armature 'p2 and through it to operate the loekbol t. The magnet-coils are mounted on a spring-controlled frame p, which is actuated by a tumbler-cam p1, operated by a suitable handle. (Not shown.) Then the tuinblei-cam 2; is operated, the frame fr will be retracted against the tension of its springs, will draw back the magnet-coils and the armature p2, and will retract the platepfgagainst the shoulder of which the armature p2 bears.

The circuits employed are as follows: l\Vire 2O leads from one of the contacts N, through the magnet-coils p, before referred to, to the battery or other source of electrical energy, (herein marked X.) From the other pole of the battery is led a wire 2l rlhis wire 2l has two branches 22 23. The branch 22 leads to the other contact N, before described. The wire 23 leads to the tumbler-cam p, before referred to. In the lock-casing is located a springcontact il". rlhis spring-contact is so arranged that when the magnet and its armature and the bolt are in their forward position- 1'. c., when the tumbler-cam p1 stands at right angles to thc position shown in Fig. wthe contact will be Very close to, but not of course touching, the magnet -carrying frame. Then the 1nagnetearrying frame and connected parts are drawn back, as shown in Fig. 5, the contact is forced back with it. From this contact is led a wire 2i, which connects at any suitable point with the wire 22, leading to the contact N. Branching from the wire 2f) at any suitable point is wire 27, which leads to one terminal of a bell, buzzer, or other suitable alarm. The other terminal of the alarm is connected by a wire 2S to one of the spindles a, herein shown as the upper one. 'lhe wire 2f) connects the wire 22 with the contact-strip (),which connects the brushes K, before described.

\Vith the circuits arranged as described it will be obvious that when each pair of brushes II and I is bearing upon the ends of the conducting bar or section (Z2 of the ring l) a circuit will be established from the battery,

through the wires 2']v 23, to the tumbler-cam ji", and from thecontactvy", through the wires 2- 22, contact N, brush I, conducting-section d2, brush II., metal conductor M, brush Il of the upper controller, connecting-section (Z2,

brush I, the contact N, and the wire 20, including the magnet-coils p', to the battery.

As soon as the tumbler-cam is operated to open-the door the metallic magnetcarrying frame of the lock mechanism will be'brought into contact with the spring-contactp, which, as before said, lies close to it. This will close the circuit heretofore described and set up a current throughthe magnet coils, causing the magnet to attract its armature. The further movement of the tumbler-cam will cause the magnet-armature land locking-bolt to be drawn back together, and the door may be opened. If, however, any attempt is made to open the door at a time when either of the circuit-controllers is set so that the brushes IIY and I are not on the ends of the conducting-section d2, the circuit will be established through the alarm. In this case one or both of the brushes K will be resting on the metallic plate E, according as one or bothof the controllers are improperly set. Supposing the upper controller to be improperly set, the circuit will be established from the battery, through the wires 20 27, the alarm, and the wire 28, to the spindle c. -From this spindle the circuit passes to the upper disk E, the upper brush K, the contact O, the wires 29 22 24, to the spring-contact p6. If now the tumbler-cam be operated in an attempt to open the door, the circuit will be closed by means of the metallic frame of the lock, be-

fore described, through the wires 23 and 2l,

to the battery, thereby sounding the alarm. In case the upper disk is properly set and the lower disk improperly set a' similar circuit will be established, also sounding the alarm.

The operation is as follows: The operator first brings each of the combination disks to the startingpoint of the combinationnamely, to the nick marked 0. Inasm uch as this nick is spaced at a considerable distance from the adjoining nicks the operatorcan readily tell when the spring-detent or feeling-pin drops into this notch. IIe now turns the spindle and each nicked disk until the detent engages the nick which indicates the point at which the circuit-controllin g brushes II I are in contact with the conducting-section d2 of the disk D. If, for instance, the combination for the upper disk be 5, the operator after bringing the disk to the nick marked 0 turns it to the right until the feeling-pin drops into the iifth notch. In the same way if the combination for the lower disk be 7 this disk is turned from the starting-nick until the feeling-pin 'drops into the seventh notch. Each nicked disk having beenA properly set, the door can now be opened by turning the knob, the circuits being established through the magnets of the lock, as above described. If, however, any unauthorized person attempts to open the lock, unless he is in possession of the combination and succeeds on the first attempt to set each disk on the proper number an attempt to open the lock by turning the handlel will establish'a circuit, as'before described,

and cause the alarm to sound. It is obvious, therefore, that the lock cannot be opened until the circuit-controllers or brushes are prope'rly set and also that any attempt to open the latter resulting in improperly setting the brushes will cause the alarm to sound and give a notification that the lock is being tampered with.

While the mechanism above Vdescribed as an entirety is an eii'ective means for carrying the invention into eiect, it is to be understood that the invention is not limited to the specific details thereof and that parts thereof may be used without employing the whole. For instance, under certain circumstances, as in a very simple lock, one set of circuit-controllers might be used. On the other hand, in case it be desired to increase the security of the combination more than two sets of controllers may be used. So,too, while it is Yconvenient to arrange the circuit-closer so that it will be operated by the tumbler-cam of the lock, such arrangement is not necessary. Again, while the lock mechanism shown and described is the most effective one known to' me,other lock mechanisms may be substitutod therefor, and in general manychanges may be made without departing from the spirit-of the invention, which within its scope is gen- Aeric in its nature.
